Hi @michelle_i_am, these studies look really good! - In #2 I might have placed the spine a little deeper, and made it a little thicker toward the lumbar section. - The ribcage and pelvis are not always correctly placed, but that's another lesson :) Just wanted to make you aware. For me it got a lot easier to draw the spine once I learned to draw the pelvis and ribcage (especially the ribcage). Hope this helps :) Keep up the good work!
